Some Chemical Group Co., Ltd. is the Shaanxi Provincial Party Committee, the provincial government to implement the "Western Development" strategy, give full play to the advantages of Shaanxi coal resources, starting from the cultivation of energy chemical pillar industries, according to modern enterprise system requirements, restructuring Developed state-owned energetic energy chemical companies are the backbone enterprises in Shaanxi energy chemical industry, and is also the main body of development and construction of coal extension in the province.
In the 17 years, the Group has formed "coal mining, coal chemical" two major main business and "coal-fired power generation, steel smelting", "coal mining, coal chemical" main and "coal-fired power generation, steel smelting" , Mechanical manufacturing, building construction, railway investment, science and technology, finance, modern service, etc. Related multi-complementary, coordinated development of industrial patterns. There are more than 60 wholly-owned, holding, holding, and shareholding enterprises, 3 listed companies, with a total employee, total assets of 540 billion yuan. In 2020, Shaanxi Coal Group has produced 1.95 billion tons of coal, producing 18.81 million tons of chemical products, producing thicker steel, 398 million degrees of power generation, producing cement products 7.78 million tons. The year-round revenue is 34.2 billion yuan, and the total profit is 17.3 billion yuan. In 2015, I entered the "Wealth" world of "wealth" world, I will enter the list for 6 consecutive years, and the rankings are steadily upgraded.
Metal powder introduction:
Metal powder refers to a metal particle group having a size of less than 1 mm. Including a single metal powder, alloy powder, and some difficult-melted powder having metal properties, is the main raw material of powder metallurgy. Metal mononas is generally silver white. When the metal is under certain conditions, it is black powder. Most metal powders are black.Metal powder belongs to a loose substance, and its performance is comprehensively reflecting the properties of the metal itself and the characteristics of the characteristics of individual particles and the characteristics of the particle group. The performance of the metal powder is generally divided into chemical properties, physical properties and process performance. Chemical properties refer to metal content and impurity content. Physical properties include the average particle size and particle size distribution of the powder, the specific surface and true density of the powder, the shape of the particles, the surface morphology, and the internal microstructure. Process performance is a comprehensive performance, including the fluidity, loose density, resonance density, compression, formability and sintering dimension, and the like. In addition, the powder is also required for some special purposes.There are other chemical and physical properties such as catalytic performance, electrochemical activity, corrosion resistance, electromagnetic properties, and internal friction coefficients. The performance of the metal powder depends to a large extent on the production method of the powder and the process of making it.
